What is the pstats module in Python?

The pstats module in Python is used for analyzing profiling data collected by the cProfile module. It helps in understanding the performance of your code.

How do I use the pstats module to analyze my profiling data?

You can use the pstats module by importing it and loading your profiling data from a file. Then, you can use methods like sort_stats() and print_stats() to analyze the data.

Can you give me an example of how to load and analyze data with pstats?

Sure! Here's a simple example:

import pstats

p = pstats.Stats('my_profile.prof')
p.sort_stats('cumulative').print_stats()

This will load the profiling data and print it sorted by cumulative time.

What are some common metrics I should look for in the output?

Common metrics include total time, cumulative time, number of calls, and the average time per call. These help identify bottlenecks in your code.
